Chronic Lateness or Total Exploitation?

It's true. This week I've been late every single day. One time because my of my car's unfortunate, another because the day before i left the office at midnight the night before.
Today, well, partially because I woke up tired from yesterday and only left home 9h15 (risky business), also because i couldn't find a spot for the life of me, and spent about 20min looking for one.
Now, as much as I agree that being here 10am isn't what I'm supposed to do, I can't be here at nine in the morning either. When I wake up at 8am, I have 30min to have breakfast and 30min to shower, and if I respect that with precision - tough task when you just woke up - I can be here at 9h30.
If I were to be here at 9am, I'd have to wake up 7h30. Now, I don't have a fixed time to leave the office. If I had anything near a schedule, I'd be here at nine and leave at six (which adds up exact 9 hours of work). But that's unreal, I never get home before 9 pm, 8:30 when I'm lucky as fuck.
I usually go to bed at 2am, given that I have to eat dinner and well, take care of my personal shit. I have five hours of the day to myself, at most. Going to bed at 2, if I wake up at 7:30, that makes for 5 hours and a half of sleep.

Is it incredibly terrible to allow me thirty minutes of tolerance in the morning? Because I don't usually see jobs coming in that early, and when they did, even being late, I've solved them.

Fuckers. Fuck. Fucking Fuck.
